What is the bond type and molecular polarity of PCl\(_3\)?
Answer (3)
It is covalent bonding. The electrons are shared between the phosphorus and the chlorines.
covalent bonding is when electrons are shared between two elements.
molecular polarity is a little bit complicated, but I will try to explain ;) PCl3 is an alternation on tetrahedral molecules. It means that P has one lone pair of electrons. This pair of electrons are only attracted to the P nuclei and thus a greater freedom of motion. This means that their orbital is bigger and this pushes the 3 Cl atoms closer together. The angle between each Cl now is 107 and the angle between Cls and P is greater than 107. Now, due to this shape, and also electronegativity (Cl is more electronegative than P meaning that it tends to hog the electrons they share closer to itself), PCl3 is polar. Electrons that are shared tend to flow closer towards the Cl than the P side. Therefore, on the Cl side of the molecule it's, more negative. On the P side, it's more positive.
In the given question, bond type for the **molecule ** PC l 3 is covalent bond and molecular **polarity **of PC l 3 is polar in nature, respectively.
**Polarity **is caused if it has an uneven distribution of electrons, causing one end of the molecule to be slightly **positive **and the other end to be slightly negative.
The bond type of PC l 3 is covalent. Covalent bonds form when atoms share electrons to achieve a more stable electron configuration. In PC l 3 , the phosphorus atom shares three of its valence electrons with three chlorine atoms to form three covalent bonds.
The molecular polarity of PC l 3 is polar. In PC l 3 , the three chlorine atoms exert a stronger pull on the shared electrons, causing them to be slightly negative, while the phosphorus atom is slightly positive. This creates a dipole moment, making the molecule polar.
Therefore, PC l 3 has **covalent **bonds and it is a **polar **molecule.

PCl 3 has covalent bonds, with phosphorus sharing electrons with chlorine atoms. The molecule is trigonal pyramidal due to a lone pair on phosphorus, making it polar with a distinct charge separation. The chlorine atoms are slightly negative while phosphorus is slightly positive.
